Health-related quality of life in patients with alopecia areata: Results of a Japanese survey with norm-based comparisons.

ABSTRACT: Alopecia areata (AA) is a non-scarring hair loss disorder affecting approximately 2% of the global population. AA is reported to have a significant negative impact on the emotional and psychological well-being of the patients. This study aimed to evaluate the health-related quality of life (HRQoL) of Japanese patients with AA in comparison to the Japanese population norms (national standard values for Japanese) using Short Form Health Survey 36 Item Version 2.0 (SF-36v2). The study also aimed to access the negative effect of AA on patients' daily lives and the proportion of patients having anxiety and/or depression. This cross-sectional, non-interventional web-based survey study included 400 participants aged 17-84 years currently suffering from medically diagnosed AA. The assessment tools integrated in the online questionnaire included SF-36v2, the Dermatology Life Quality Index (DLQI), and the Hospital Anxiety and Depression Scale (HADS). All outcome measures from the tools were evaluated across the study population. SF-36v2 subscale scores for patients with AA revealed lower scores specifically for mental health (45.7 ± 10.1 points), social functioning (45.8 ± 10.9 points), vitality (46.2 ± 9.8 points), and role emotional (46.9 ± 11.6 points) as compared to the Japanese population norms of 50 ± 10 points each. The DLQI questionnaire-based analysis indicated that 32.1% of respondents showed a moderate to extremely large effect on their lives; and HADS-A (anxiety) and HADS-D (depression) scores categorized 46.0% and 41.8% respondents as doubtful-to-definite cases, respectively. Multivariate linear regression revealed that hair loss range, age, comorbidities, and depression significantly worsened DLQI scores. In conclusion, the results of this survey demonstrated that a significant decrease in the HRQoL scores was observed in Japanese patients with AA in comparison with the national norms. Hence, emphasis on mental health is crucial for AA management.

Project description:IntroductionIndividuals with alopecia areata (AA) may experience significant impacts on their health-related quality of life. The novel Alopecia Areata Patient Priority Outcomes (AAPPO) questionnaire has been developed to assess hair loss signs, emotional symptoms, and activity limitations associated with AA. The objective of this study was to evaluate psychometric properties and establish scoring of the AAPPO in adults and adolescents with AA.MethodsScoring and measurement properties of the AAPPO were examined using baseline and 2-week follow-up data from a prospective, noninterventional, web-based study of 121 patients with AA (85 adults aged ≥ 18 years, 36 adolescents aged 12-17 years) with Severity of Alopecia Tool (SALT) ≥ 25% scalp hair loss.ResultsExploratory and confirmatory factor analysis supported four single Hair Loss (HL) items, an Emotional Symptoms domain (ES; 4 items), and an Activity Limitations domain (AL; 3 items). Among all patients, the multi-item ES and AL domains had strong internal consistency (α ≥ 0.87); all HL items and domain scores had strong test-retest reliability (weighted kappa or intraclass correlation coefficients ≥ 0.78). All HL item scores demonstrated strong construct validity (r ≥ 0.52) compared with the patient-reported Alopecia Areata Symptom and Impact Scale (AASIS) hair loss subscale score; ES and AL domain scores exhibited strong construct validity (r ≥ 0.66) compared with the SF-36 Mental Component Summary (MCS) score. Using SALT scores, HL mean item scores were better (lower) in the 25-49% SALT subgroup versus those with highest SALT scores (76-100%); however, ES mean domain scores were better in the SALT 76-100% subgroup in the same comparison (p < 0.0001). Using AASIS and MCS score-created subgroups, ES and AL mean domain scores demonstrated hypothesized differences across subgroups (all p values < 0.0001).ConclusionThe AAPPO questionnaire is a reliable, valid disease-specific measure of hair loss severity and impact in individuals with AA.
